Do you think light speed can be exceeded?

This week's Question: The European Organization for Nuclear Research, or CERN, reported that a neutrino beam fired from a particle accelerator near Geneva to a lab 454 miles away in Italy traveled 60 nanoseconds faster than the speed of light — a claim that potentially questions Einstein's 1905 special theory of relativity. Some physicists say neutrinos theoretically can travel at different speeds depending on how much energy they have, and mysterious particles, whose existence is still only theorized, can move with similar speeds. Other physicists, however, say that the CERN findings are the result of measurement errors since tracking neutrinos is very difficult. What do you think? Do you think light speed can be exceeded?

Flexible CIGS Solar Cells - 18.7% World Record Efficiency

New technology yielding flexible solar cells was developed by scientists at Empa, the Swiss Federal Laboratories for Materials Science and Technology. Key to the breakthrough is the control of the energy band gap grading in the copper indium gallium (di)selenide semiconductor, or CIGS, the layer that absorbs light and converts it into electricity.

Will we set foot on Mars?

  This week's Question: NASA recently unveiled its new "Space Launch System," which will be designed to carry the Orion Multi-Purpose Crew Vehicle, as well as important cargo, equipment, and science experiments to Earth's orbit and destinations beyond. "Tomorrow's explorers will now dream of one day walking on Mars," said NASA Administrator Charles Bolden. NASA's rovers, too, continue to learn more about the makeup of the planet. What do you think? Will we set foot on Mars?

C37.90.1: IEEE Standard for SWC Tests for Relays and Relays Systems Associated with Electric Power Apparatus

Two types of design tests for relays and relay systems that relate to the immunity of this equipment to repetitive electrical transients are specified. Test generator characteristics, test waveforms, selection of equipment terminals on which tests are to be conducted, test procedures, criteria for acceptance, and documentation of test results are described. This standard has been harmonized with IEC standards where consensus could be reached.

Wind Turbine Placement Research Facility

Researchers from California Institute of Technology have been conducting a field tests at an experimental two-acre wind farm in northern Los Angeles County. The farm, known as the Field Laboratory for Optimized Wind Energy (FLOWE), houses 24 10-meter-tall, 1.2-meter-wide vertical-axis wind turbines (VAWTs) - turbines that have vertical rotors.

Electronic "Bucket Brigade" Could Boost Solar Cell Voltages

If solar cells could generate higher voltages when sunlight falls on them, they’d produce more electrical power more efficiently. Ferroelectrics - materials with an overall electrical polarization - can develop very high photovoltages under illumination. Berkeley Lab researchers have now figured out exactly how this photovoltaic process occurs.
